Abstract

We discuss Born-Infeld on the noncomm utativ e two-torus as a description of compactified
string theory. We show that the resulting theory, including the uctuations, is manifestly
invariant under the T-duality group SO(2; 2; Z ). The BPS mass ev en has a full SL(3; Z ) x SL(2; Z ) U-duality ... read more symmetry . The direct identification of the noncomm utative parameter
Ø with the B-field modulus ho wever seems to be problematic at finite v olume. show less
